About this project

3 Phase Induction Motor With Soft Start

Objective: Implement a soft start system for a 3-phase induction motor to reduce mechanical and electrical stress during startup.

Context: Industrial motors in India often suffer from high inrush currents and wear during startup, leading to costly maintenance and energy inefficiency.

What you'll build: Using TRIACs or SCRs, Arduino or PLC, and voltage/current sensors, you'll develop a motor control algorithm and soft start circuit. An LCD will display real-time parameters, and you'll test motor performance improvements.

Deliverables: Soft start motor prototype, performance data, and a concise project report.

Milestones

1. Motor parameter analysis

10 marks 7d

Collect and tabulate the key electrical parameters of your specific 3-phase induction motor, including rated voltage, current, power, speed, and torque. Submit a concise report with measured or datasheet values, calculation methods, and any relevant assumptions. Ensure all data is clearly labeled and directly applicable to subsequent control and circuit design steps.

2. Control algorithm development

10 marks 7d

Develop and document a control algorithm that enables soft starting of the induction motor by gradually increasing voltage or frequency. Submit a flowchart or pseudocode detailing each step, including ramp-up logic and protection features. The algorithm must be tailored to your motor's parameters and ready for translation into circuit or code implementation.

3. Soft start circuit implementation

15 marks 7d

Build the soft start circuit based on your control algorithm, using appropriate components (e.g., relays, thyristors, microcontroller). Submit a schematic diagram, component list, and annotated photos of the assembled circuit. The circuit must demonstrate controlled voltage or frequency ramp-up, with all connections and safety features clearly shown.

4. Motor performance testing

15 marks 9d

Test the motor using your soft start circuit and record performance data, including current draw, voltage, and acceleration profile during startup. Submit a report with test setup photos, measured data, and a comparison to direct-on-line starting. Clearly highlight improvements in inrush current and smoothness of startup, supported by graphs or tables.
